Economic Engineering for Supply Chain Management: Mitigating the Bullwhip Effect Using PID Control

The purpose of Supply Chain Management (SCM) is to maximize and stabilize the flow of goods through a supply chain. Disruptions to this flow, such as the Bullwhip Effect (BWE), have become increasingly severe and dynamic, challenging current methods for counteracting these disruptions. This thesis develops a systems and control framework for...

Modelling of material flow and size distribution of ore in a stockpile at Tara Mines, Ireland

This study aims to understand the material behaviour of ore inside a coarse ore stockpile by discrete element modelling. This is of importance since the stockpile is the last stage to control the size distribution of ore in the ore handling system before feeding the grinding circuit. An optimal size distribution is required for efficient...

Electromagnetic detection of metals in waste materials

The aim of this study is to detect and count metal particles in the flow of bottom ash product after separation by the eddy current separator. By counting, the grade of the material can be determined if the average particle mass is known. The focus of this study is on electromagnetic detection of ferrous and non-ferrous metals. By several...
